Hello Aviral,
There are various options after B.Sc, but that depends on the stream or subject in which you completed your B.Sc.
The basic and most preferred option after B.Sc is to go for M.Sc or some other research oriented work. After completing your research you can become a professor or continue research. Join some big research centres such as BARC. Or join a company where too you will be doing product based research. You may also go for civil services, or go for MBA. You also have the option to do MCA if you want to join the IT sector. Other option is to go for B.Ed, Technical writer, Government sector jobs such as that of Railways or Bank PO.
Hope this Helps
